CHAPTER 11: Ethernet Traffic Analysis
11. Ethernet Traffic Analysis
Traffic provides a report of Ethernet network utilization and activity.
The SCAN-LAN VI monitors live traffic on 10BASE-T Ethernet networks
and continuously displays the percentage of network utilization, peak
traffic, and collisions on the screen along with a bar-graph display of
network activity. An audio tone provides feedback of network activity.
Test results are saved in the SCAN-LAN VI’s memory and can be printed
when the test is completed. The printout includes a graph of network
activity over time showing average utilization, peak utilization, percentage
of collisions, packet counts, and jabber conditions. For 10BASE-T networks,
the SCAN-LAN VI automatically generates link pulses to activate the hub
and reports whenever a link state with the hub is lost.
Because the Traffic test runs continuously, use the AC/Mains adapter
if the test is to be run for an extended period.
The SCAN-LAN VI’s Traffic test reports: Network utilization percentage,
peak traffic, and collisions.
The Traffic test also detects: Jabber, loss of link connections (10BASE-T),
and wrong polarity.
11.1 Running the Traffic Test
1. Connect the SCAN-LAN VI directly to the network either at the
10BASE-T hub or at the end of a cable segment.
2. Switch dial to TRAFFIC. (Press arrow keys to change the cable test
standard and SAVE (F4) or ENTER to select a cable test standard.)
3. Press ENTER to clear the last Traffic test from memory and start a new
test.
CAUTION
Auto power-down is disabled during the Traffic test. Use the AC/Mains
adapter to power the SCAN-LAN VI for extended Traffic monitoring.
